lIMPROVED R'OLLERS FOR WRINGING'MACHINES'.

Specication forming part of Letters Patent No. 34,142, dated January 14, 1862.

To all whom t may concern:

Be it known that I, JOHN J. I-IALEY, of South Dedham, inthe county of Norfolk and State of Massachusetts, 'have vinvented a new and useful Improvement in Rollers for \Vringing Machines, the.; and I do hereby declare the same to be fully .described in the following specification and represented-in the accom- 'panying drawings, of which- Figure vl denotes an elevation, and Fig. 2 a central and longitudinal sectionhot thesaid roller.

It is a fact Well known to manufacturers of wringing-machines wherein the water is te be expressed from the clothes by passing hetween tworollers, which have solid ormetallic shafts surrounded by thick tubes of indiarubb'er, and in many other machines Where india-1'ubber rollers are to be united to metallic shafts, especially when these shafts are small in proportion to the size of the rollers, that it has lbeen lound almostvimpossible to so connect the rubber with the shaft as to prevent the latter from turning around on the form erwhen a very great pressure was brought upon the rubber. To effect a'l'ii'incoxi'nection between the two, various expedients have been resorted to. The surface of the ;sli'a ft"has been coated with india-rubber and various other cemeuts and the tubing drawn closely on the shaft; but the cement would not ad-.-

here and under small force applied ttl it peeled ott, and of course allowed the tubing` to revolve. The surfafe of the shaft has also been made rough oit-with teeth. VThis soon cut holes in the rubber and rendered the tubgrooves in the shaft; but this completely failed ol reaching the desired result.

To find alneans by which a rubber tube Others have for-mediongitudinali purpose I prefer good copal varnish, which is not only very adhesive and firm, but is not iii'- juriously acted' onyby the iron over ,thiscoating,and While the varnish is in a soft state I closely wind a small twine or cord l? spirally or at right angles to the axis of the shaft-or instead of the twine a strip of stout cloth or canvas may be tightly Wound. To this I apply one or more coatings cof india-rubber or other adhesive cement and allow the same't'o become dry. Next I apply anothercoating to the one already dried. Next I give y*the chamber or bore of the tube B one or more coatings of said rubber or other cement.V The rubber tube is next pressed 'or Vforced onV the shaft and the whole laid aside t0 dry. I .have found that when india-rubber tubes are connected'with metallic shafts in=.my improved manner their connection is sodirm and Aenduring that it is impossible to separatejh'm -by any ordinary force.

I do not claim a roller Amade ofi shaft and an india-r ubber covering placed concentrically on 'such shaft; nor do I claim a helix of' cord and a coating of glue or cement vas aineans of connecting one thing to another; but

' What I claim as my invention islily-improved roller,.made substantially as described.
